Adding second HDD as Home

After poking around some posts (and Google) I'm not sure I came across the solution to what I'd like to accomplish.

I have a second hard drive that I would like to use as /home. Is it as simple as using this tool, selecting format to erase it, and then select edit partition > Linux home partition?

Here's my fdisk -l, it's the drive HGST and I'm guessing it shows as sda1 because I last used it in a Mint install, but I intend to wipe it if needed:

If there is no valuable data on the disk try it and report the result.

You can do that only as root and from tty.

Those would be the steps I've been searching for and not finding. :wink:

Thought this looked promising, if I can get my amateur head wrapped around it: Adding new hard drive as /home after installation

There is an easier method - described in this topic

It appears to be correct according to this df -hl information because I can see that /home resides on a partition much larger than my 256gb SSD. :grin:
